Summary
Sharbel A. walks through five practical use cases for GPT-6 Astra, OpenAI’s latest model with significantly improved computer-use capabilities. Released in early September 2026, Astra scores around 72% on the OSWorld computer-use benchmark — up from 65% on the previous model — and operates roughly twice as fast, though the presenter is careful to note these are OpenAI’s own numbers.
The five use cases covered with live demos include: email triage and follow-up drafting (where Astra browses a real inbox and writes replies); 3D game generation from a single text prompt, producing a playable browser experience including physics and sound; website building where the model writes, runs, screenshots, and iteratively fixes its own output until the site works end-to-end; security auditing that scans a given website for vulnerabilities and patches them; and direct operation of creative software like Blender and video editors, clicking through the UI rather than just generating assets.
The presenter is candid about limitations throughout: Astra still makes mistakes, runs slower than a human doing the same task manually, and typically gets about 90% of the way to a finished result before needing additional prompting. The video is particularly useful for developers and creators evaluating whether GPT-6 Astra’s agentic loop is mature enough to replace manual steps in their existing workflows.
